The world has began the 4th industrial revolution with internet of things, or the method for connecting the objects around us using internet and thus making them easy for us to control. However, the problem of it is that objects related to ioT (internet things) seem so mechanical, angled, and unfriendly. Thus, the character industry, which is much friendly with people but has limitation with growth itself was collaborated with ioT by a company named KT(Korea Telecom).
The two characters used in this company are named IO (for the black one) and IT (for the white one). For advertisement, new webtoon and short videos have been made for these two characters. These two machines contain speaker, home camera, lamp, and gas valve. Moreover, since they are characterized machines, they are not only useful for their mechanical function, but also as pretty interior decorations.
In my opinion, character-ioT is such an innovating technology that has loads of possibilities. For example, if robot engineering is added on this technology, the bound of functions of the characterized machines are going to get wider. Also, if 3D printing skills are added on it, mass production of machines will be supported by making hardware of the machines faster and easier.
